FURMAN D. SPEAR, OF BROOKLYN, NEW YORK, ASSIGNOR TO ARMSPEAR MANUFACTURING COMPANY, OF NEW YORK, N. Y.

SWITCH-LAMP SOCKET.

SPECIFICATION forming part of Letters Patent No. 718,583, dated January 13, 1903.

Application filed February 23, 1897; Renewed July 31, 1902. Serial No. 117,737.- (No model.)

To all whom it may concern:

Be it known that I, FURMAN D. SPEAR, a citizen of the United States,residing in Brooklyn, Kings county, and State of New York, have invented anew and useful Improvement in Switch-Lamp Sockets, of which the following is a specification.

This invention relates especially to the construction and arrangement of sockets for switch-lamps, and has for its object the provision of a simple, durable, and eifective socket.

To attain the desired end, the invention consists in certain novel and useful combinations or arrangements of parts and peculiarities of construction and operation,all of which will be hereinafter first fully described, and then pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a switch-lamp to which the invention is applied. Fig. 2 is a vertical axial sectional view of the bottom portion of the lamp and the socket at line a a of Fig. 1. Fig. 3 is a bottom plan view of the socketplate removed from the device.

Like numerals of reference Wherever they occur indicate corresponding parts in all the figures. 7

l is a switch-lamp provided with a socketbase 2, secured thereto. This base is open through its center at 3 and is provided with a stop or shoulder 4. I

5 is a loose movable socket having a flange or projection 6, arranged to come in contact with the stop within the base 2. The socket 5 may be provided with guide projections 7 at the corners.

8 is an opening in the socket for the reception of a switch-staff 9.

10 is a spring held between the flange 6 of the socket 5 and the bottom of the lamp-body.

In assembling the device the socket 5 is dropped into place, the spring 10 placed thereover, and then the foot is secured to the lamp-body.

It will thus be seen that a very effective support for a switch-lamp is provided, simple and cheap to construct and easy to assemble and apply.

Having now fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. In a switch-lamp a base or foot having a vertical perforation therethrough of two different diameters, as shown; a loose socket provided with a projecting flan ge,and a spring located between said socket and the body of the lamp, the whole combined and arranged to operate, substantially as shown and described.

2. A switch-lamp support in which is comprised a base or foot having a perforation therethrough, the lower portion of which is rectangular in cross-section, and the upper portion of larger diameter than the lower portion in combination with a socket loosely held in said perforation by aprojecting flange, and a spring located between the socket and the bottom of the lamp,substantially as shown and described.

3. In a device of the character herein specified, the combination with the base-piece and spring, of a loose, movable socket provided with projecting guide-ribs, substantially as shown and described.
